PS4-MT50 Monotorr Heated Getter Gas Purifier - 50 to 100 l/min

Rare Gas/Nitrogen/Hydrogen Purification - PS4-MT50

The High Flow MonoTorr purifier provides sub-ppb impurity removal in Hydrogen, Nitrogen and Rare Gases at flow rates up to 150 slpm. Each purifier comes fully enclosed and is designed for wall mounting. Standard features include an exhausted enclosure with separate bay for electronics, separate doors for gas piping system & electronics, and an exhaust collar with fan. An optional package (for Hydrogen units) includes a Hydrogen leak detector with automatic shutdown, electronic isolation, and a Nitrogen purge system with flow sensor.

Heated getter purifiers provide the most complete removal of impurities for Rare Gases, Nitrogen and Hydrogen. The metal getter forms an irreversible chemical bond with all oxide, carbide and nitride impurities. The MonoTorr is the only purifier technology capable of removing Hydrocarbons and Nitrogen from process gases.

Standard Features

Valves: Automatic inlet, outlet, and bypass valves are standard.

Life Status Indicator: Getter life status indication provided on control panel.

Controller: PLC based controller with text LCD

Ultrafine 0.003µm Particle Filter

Optional Features

N2 purge system for Class I Division II Environment (H2 only)

MODBUS Communication

Hydrogen Leak Sensor (H2 only)

Emergency Off Button (EMO)
